some more ...i have so many things to solve but i dont know where to start from ,so urgent help needed!!!

us drawing the diagram for you won't help, since we'd use a graphing utility and you won't know what happens. if you have any specific questions about graphing, just say so and i'll try to answer them. otherwise i'll find a from question 2

Now we are told that the graph passes through (2,5), this means when x = 2, y = 5

Hopefully you can take it from here. if not, ask SPECIFIC questions about graphing
